Off-hand, I can think of so many subjects that will be deeply affected by a 6-3 court - gay marriage, tax codes, unions, abortion, free speech, corporate/business freedoms, environmental issues, civil rights, voting rights, sentencing laws, the list is so long and so dangerous....

And a very conservative Supreme Court is going to be Trump's actual wall, built to keep all sense of ethics, morality and legality away from his sticky fingers and double-dealing. They won't let him be touched.

I'm sure the WH will be screaming that there is a dark state conspiracy against Trump if the Democrats try to keep him from packing the court, like the Republicans did to deny Obama his last Supreme Court vacancy appointment.

I doubt that the Dems will even try very hard to keep the next Bork from being approved anyway. The one thing they have in common is that they are all politicians.

It won't be a 6-3 court... not yet, anyway, unless (perish the thought) Ginsberg passes away or something within the next 2 years.

Kennedy was still a Republican (Reagan) pick, so his replacement doesn't change the overall 5-4 balance between more conservative versus more liberal oriented justices. He was a more moderate voice on the court though, so there is some concern that his replacement might be more extreme when it comes to certain social issues like access to abortion services or LGBT rights.

I imagine it will be a pretty contentious fight to find his replacement. Only 3 Democrats defected and joined the unanimous Republican bloc in confirming Gorsuch the last time. I imagine with the stakes even higher this time, there will be a lot more pressure on those Dems not to buckle. And John McCain has already proven he's a maverick when it came to saving Obamacare, so if he and one more Republican defect, Trump might have a tough time getting anyone confirmed. At least if they are too extreme.

It will be interesting to see what effect the Mueller report has as well, once he presents his finding to Congress and Trump's criminal antics are laid to bare...

The GOP holds 51 seats in the chamber, but only 50 Republicans will likely vote as Sen. John McCain, R-Ariz., fights brain cancer. If all Democrats unite in opposition to Trump's court pick, one GOP defection would sink the nomination. However, three vulnerable Democrats voted to confirm Gorsuch last year, and they could potentially take their cues from moderate Republicans once again.

A … possible concern is that the country needs a check against a bad-behaving or law-breaking President. But the Constitution already provides that check. If the President does something dastardly, the impeachment process is available. No single prosecutor, judge, or jury should be able to accomplish what the Constitution assigns to the Congress. … The President’s job is difficult enough as is. And the country loses when the President’s focus is distracted by the burdens of civil litigation or criminal investigation and possible prosecution.
